Additional Details:

The UM2300 series offers a range of standoff voltages to accommodate various application requirements. The clamping voltage is the maximum voltage that the device will allow to pass through during a surge event. The surge current capability indicates the maximum current the device can withstand without failure. Microsemi offers this TVS diode in various packages, including surface mount and through-hole options, to suit different board assembly needs.

These TVS diodes are particularly useful in protecting I/O ports of microcontrollers and other integrated circuits, safeguarding them from damage caused by ESD strikes. In data line protection applications, they prevent data corruption and hardware failures resulting from voltage surges. In power supply protection, the UM2300 helps to filter out transient voltages and ensure stable power delivery to the downstream circuitry. Automotive applications benefit from the robust protection afforded by these diodes, safeguarding sensitive electronic control units (ECUs) from the harsh electrical environment of a vehicle.
